Social network phenomenon

Branding plays a huge part in my daughters life. As a 11 year she is becoming increasingly aware of brands and the high value placed on a logo. No longer will a basic plain supermarket tshirt be suffice but due to advertising (offline and online) as well as her peers she now aspires to branded goods such as Holister, Jack Wills and other such makes. One Huge part of her leisure time is spent using social media sites such as Facebook, Twitter, vibe and Instagram. Such programs are used to communicate amongst her friends instantly. For advertisers the social media is a Huge tool for advertising thier products and using sites such as Facebook, a company can directly target the clients specifically and advertise to the individual. So not wasting time advertising to the mass. An example of this is if my daughter was to 'like' a Jack Wills page on Facebook not only does that advertise the brand to all her friends on the site, it also allows Jack will to market direct to her and her friends through social media and other online media tools.
